#define NLMSG_NEXT	(		nlh,
			len
	)

Value:

((len) -= NLMSG_ALIGN((nlh)->nlmsg_len), \
                             (struct nlmsghdr *) \
                             (((char *)(nlh)) + NLMSG_ALIGN((nlh)->nlmsg_len)))

#define NLMSG_OK	(		nlh,
			len
	)

Value:

((len) >= (int) sizeof(struct nlmsghdr) && \
                           (nlh)->nlmsg_len >= sizeof(struct nlmsghdr) && \
                           (int) (nlh)->nlmsg_len <= (len))

#define RTA_NEXT	(		rta,
			attrlen
	)

Value:

((attrlen) -= RTA_ALIGN((rta)->rta_len), \
(struct rtattr *) (((char *)(rta)) + RTA_ALIGN((rta)->rta_len)))

#define RTA_OK	(		rta,
			len
	)

Value:

((len) > 0 && (rta)->rta_len >= sizeof(struct rtattr) && \
(rta)->rta_len <= (len))
